Rose Plant named &#39;Tanmirsch&#39;

ABSTRACT

The new cultivar is a variety of bed rose plant having an bushy growth habit. The yellow flowers are stable in color. The plant is robust, exhibits good hardiness, and ground covering ability.

BACKGROUND OF THE NEW PLANT

[0001] The present invention includes a new and distinct cultivar of Rosa l. known by the varietal name ‘Tanmirsch’.

[0002] The plant was discovered in 1988 by the breeder in Ueterson, Germany in a selective breeding program designed to produce a yellow bed rose variety that is robust, hardy, and has a stable color. The new plant is a selection from a cross of unnamed seedlings maintained proprietary by the assignee of the present application. The plant was first asexually reproduced in 1993 and can be propagated asexually on Rosa canina rootstock.

[0003] The variety is distinguishable by its very good hardiness, stable color, and good ground covering ability. Continued observations from the vegetative cuttings in Uetersen, Germany have confirmed that the distinguishing features of this new cultivar come true, remain stable, and are retained through successive propagations.

DESCRIPTION OF THE DRAWING

[0004] The accompanying photographic drawing illustrates the new cultivar. Colors are described in part in reference to the R.H.S. Colour Chart of The Royal Horticultural Society of London.
